Volt SB220.1 Sub Bass Size:214x214mm

 8" Paper Cone Sub Bass

The SB220.1 has been optimised for bass performance in sub-woofer applications. It uses a vented symmetrical field magnet system with a long coil for large linear excursion capability. The cone uses a long fibre pulp for rigidity and with the dustcap is damped by a coat of gloss black dope. Suspension stiffness and excursion is optimised for tight control over high power transients. All mounted on a heavy duty cast chassis.

The Thiele-Small parameters are optimised for easy use in small sealed, vented or bandpass enclosures to give extended bass performance.
